Karesansui explanation

Quick answer：

Karesansui, also known as 'dry landscape' or 'dry rock garden,' is a form of Japanese rock garden design that uses rock arrangements, white sand or gravel, and occasionally plants to represent a natural landscape. It originated in the 13th century as a Zen Buddhist expression and is characterized by its minimalist aesthetic. The focus is on the use of natural materials and the emphasis on harmony, balance, and tranquility.
